I got my Scorpion 2 weeks ago and finally had the chance to take it to the range today. I already had installed the yeti grip, HBI charging handle and trigger. Although I also have the HBI trigger spring, I wanted to shoot it first with the oem spring. After zeroing the Vortex Sparc 2 red dot sight I bought for it, it chewed the center section of the target. The first 50 rounds were Perfecta, and the next 150 rounds were Freedom Ammunition reloads. Not a single problem was encountered. And yes, the trigger was on the heavy side.
